Short Answer
A population has a mean of µ = 80 with σ = 20.
a. If a single score is randomly selected from this population, how much distance, on average, should you find between the score and the population mean?
b. If a sample of n = 4 scores is randomly selected from this population, how much distance, on average, should you find between the sample mean and the population mean?
c. If a sample of n = 100 scores is randomly selected from this population, how much distance, on average, should you find between the sample mean and the population mean?
